Hi,

Two questions :

We developed a pf app for an Onyx2, that - as an option - uses a Pbuf
and noticed that when this option is on, another pf app running on the
same machine suffers a dramatic performance hit.
The first app has a very small scene : one cube, three cylinders,
implemented in OpenGL and Performer, no special effects
The second has a rather large scene, build on VEGA & Performer, with
special effects.
Both running 20 Hz. And sharing pipes.
Before bothering you with details :
-- Is there a general rule to run several pf apps concurrent on the same
machine ?

We have to run these apps at the same time so we tried to run the simple
one on an O2, that happened to be around.
Due to the poor graphic-hardware this app pushes an O2 over its limits,
and even crashes, when other processes - like new shells - are started.
-- Is there - apart from : don't - a general rule to run performer apps
on an O2 ?

Thanks

Dirk
